Blacksmith, an AI code-testing startup, has secured $45 million in a Series B funding round, propelling its valuation to $550 million. This represents a nearly tenfold increase from its $60 million valuation less than a year ago during its Series A raise. The company, founded in 2024, offers solutions to build, test, and verify software code, addressing the growing need for quality assurance as AI coding tools accelerate development.
Co-founder and CEO Aditya Jayaprakash highlighted that while AI tools like Cursor and Codex make code generation faster, validating the quality of this AI-generated code remains a significant bottleneck. Blacksmith's platform, which evolved from a cloud provider for continuous integration workloads, now includes Codesmith, an AI agent designed to automatically fix failed code checks. The company has seen substantial growth, serving over 5,000 customers, up from 700 a year ago, and has achieved an annualized revenue run rate in the tens of millions of dollars with approximately 30 employees.
Despite operating in a competitive market with rivals such as GitHub Actions and cloud providers like AWS, Azure, and Google Cloud, Blacksmith emphasizes its speed and affordability as key differentiators. The company plans to expand its product suite to further assist developers in writing, validating, and merging software more efficiently.
